A LS-6 crate motor should have the letters XAA somewheres in the engine numbers.

Standard 9.8" deck height block like most of them. Have fun.. Great start for a build! Tall decks came in dump trucks or aftermarket so guys could put a longer stroke crankshaft in. You have exactly what you need for a great engine!
